Description

[Technical Field]

[0001] The present invention relates to a disaster prevention system that monitors abnormalities by connecting terminal devices including a fire hydrant device to a disaster prevention receiving panel, and to the fire hydrant device. [Background technology]

[0002] Conventionally, fire hydrant systems have been installed as emergency tunnel equipment to build disaster prevention systems in tunnels such as expressways and expressways, which are areas subject to fire extinguishing. A fire hydrant system includes a fire hose with a nozzle attached to the end, valves including a fire hydrant valve, and a fire hydrant valve opening / closing lever as a hydrant valve opening / closing control unit for operating the hydrant valve, all of which are housed and installed in a fire hydrant storage compartment within a housing equipped with a fire hydrant door. Two fire extinguishers are also housed in a fire extinguisher storage compartment within a housing equipped with a fire extinguisher door. Furthermore, fire hydrant systems are generally installed by embedding boxes into the tunnel wall along the length of the tunnel, for example, at intervals of 50 meters.

[0003] Additionally, fire detectors are installed inside the tunnel at intervals of, for example, 25 or 50 meters along the length of the tunnel to monitor for fires as an abnormality, and the fire detectors are connected to signal lines and transmission lines drawn from a disaster prevention receiving panel installed in the electrical room of the tunnel facilities. The fire detectors have detection areas on both sides of the length of the tunnel, and detect fires by receiving infrared energy in a wavelength band specific to the flame that is emitted from the source of a fire.

[0004] Furthermore, because road users are generally unfamiliar with operating fire hydrants, when the hydrant door is opened, an operation method nameplate is visible that shows how to operate the hydrant in an easy-to-understand manner using diagrams, etc. However, in an emergency situation such as a fire outbreak, it is difficult to use the hydrant correctly by looking at the operation method nameplate, and there is a risk that operating the hydrant will take too long and firefighting activities will not be carried out appropriately and quickly.

[0005] To solve this problem, there is known a fire hydrant device that provides visual and / or audio guidance on how to operate the fire hydrant device to help road users who are unfamiliar with operating the fire hydrant device (Patent Documents 1 and 2).

[0006] Such conventional operation guidance for fire hydrant devices includes those that optically activate a display unit to show the location of the hydrant door handle when the push button on the hydrant device's transmitter is pressed, those that optically activate a display unit to show the location of the fire hose nozzle when it is detected that the hydrant door has been opened, and those that optically activate a display unit to show the location of the hydrant valve opening / closing lever when it is detected that the nozzle has been removed. These enable even road users who are unfamiliar with operating fire hydrant devices to understand which part of the device they need to operate in an emergency such as a fire, and to operate the device correctly. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-310785 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-102380 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in an emergency situation such as a fire outbreak, there is no guarantee that road users will follow the operating instructions correctly, and even if the operating instructions are provided as with conventional fire hydrant devices, there are cases where an operation that should be performed later is performed first. Therefore, conventional fire hydrant devices are insufficient to suppress and prevent incorrect operation by road users and ensure that road users operate the device in the correct procedure.

[0009] For example, even though the fire hydrant device is guiding the user to remove the nozzle, it is conceivable that the road user may mistakenly operate the fire hydrant valve opening / closing lever first. Conventional fire hydrant devices do not respond to such erroneous operations and continue to guide the user to remove the nozzle. In this case, the road user must realize the erroneous operation and return the fire hydrant opening / closing lever to its original position. If the user does not return the fire hydrant opening / closing lever to its original position, fire water will be discharged from the nozzle held in the nozzle holder, and the discharged water will splash inside the housing and the surrounding area, causing unexpected flooding damage. In addition, the time required to remove the nozzle after the water discharge has begun may seriously hinder firefighting activities.

[0010] The present invention aims to provide a disaster prevention system and a fire hydrant device that monitor the operation of fire hydrant equipment performed by the fire hydrant device, provide operation guidance to operate in the correct operating procedure, and also provide appropriate guidance to alert users to any incorrect operation.

[0014] (Operation guidance control when a fire hydrant door is opened without a fire report) If the operation monitoring unit receives operation event information indicating the opening of the fire hydrant door without receiving operation event information indicating the operation of the transmitter, it outputs operation guidance urging the user to check for the fire and to report the fire by operating the transmitter.

[0015] (Display and audio operation guidance) The fire hydrant device is provided with an operation guide display unit that displays an instruction to operate the device at a position corresponding to each of the transmitter, the hydrant door, the nozzle, and the hydrant valve opening / closing operation unit, and also with a voice output unit that outputs the operation guide by voice; When outputting operation guidance encouraging an operation, the operation monitoring unit activates a corresponding operation guidance display unit and causes the audio output unit to output a voice message of the corresponding operation guidance.

[0018] (Operation guide for fire hydrant devices) As a fire hydrant equipment, a transmitter that notifies a fire by transmitting a fire notification signal; a fire hydrant door that is opened when a fire hose stored inside the fire hydrant device is pulled out; a nozzle attached to the fire hose and detachably held by the nozzle holding part; a fire hydrant valve opening / closing operation unit that opens and closes a fire hydrant valve provided in a pipe that supplies fire water to a fire hose; Including, The operation guide section is The event detection unit transmits operation event information indicating the operation of the transmitter based on a fire notification signal transmitted from the transmitter, and when an operation event indicating the opening operation of the fire hydrant door is transmitted based on the opening of the fire hydrant door, it outputs operation guidance to encourage the removal of the nozzle based on predetermined control, and when it transmits operation event information other than operation event information indicating the opening operation of the fire hydrant door, it outputs operation guidance to the effect that the operation is incorrect and to encourage the opening operation of the fire hydrant door based on predetermined control, When the event detection unit transmits operation event information indicating the operation of the transmitter and the opening operation of the fire hydrant door, and then transmits operation event information indicating the operation of removing the nozzle transmitted from the event detection unit based on the removal of the nozzle, operation guidance is output based on predetermined control to operate the fire hydrant valve opening / closing operation unit to open, and when operation event information other than the operation event information indicating the operation of removing the nozzle is transmitted, operation guidance is output based on predetermined control to indicate that the operation is incorrect and to prompt the operation of removing the nozzle, After the event detection unit transmits operation event information indicating the operation of the transmitter, the opening operation of the fire hydrant door, and the removal operation of the nozzle, if the event detection unit transmits operation event information indicating the opening operation of the fire hydrant valve opening / closing operation unit based on the opening operation of the fire hydrant valve opening / closing operation unit, operation guidance is output based on predetermined control to pull out the fire hose and spray water from the nozzle, and if the event detection unit transmits operation event information other than operation event information indicating the opening operation of the fire hydrant valve opening / closing operation unit, operation guidance is output based on predetermined control to indicate that the operation is incorrect and to prompt the user to open the fire hydrant valve opening / closing operation unit.

[0019] (Operation guide when the fire detector sends a fire signal) This fire hydrant device is installed in correspondence with the detection area of ​​a specified fire detector that is connected to a disaster prevention receiving panel, and when the corresponding fire detector transmits a fire signal, the operation guide unit outputs operation guidance based on specified control to check for the fire and to encourage the user to report the fire by operating the transmitter.

[0020] (Operation instructions when the fire hydrant door is opened without a fire report) If the event detection unit transmits operation event information indicating the opening of the fire hydrant door without transmitting operation event information indicating the operation of the transmitter, the operation guidance unit outputs operation guidance based on predetermined control to check for the fire and to encourage the user to report the fire by operating the transmitter.

[0021] (Display and audio operation guidance) The operation guide section is an operation guidance display unit that is provided at a position corresponding to each of the transmitter, the hydrant door, the nozzle, and the hydrant valve opening / closing operation unit and that displays a message urging the user to perform the operation; a voice output unit that outputs operation guidance by voice; Equipped with When outputting operation guidance to prompt an operation based on predetermined control, the corresponding operation guidance display unit is activated and the corresponding voice message of the operation guidance is output from the voice output unit. [Effects of the Invention]

[0022] (Effectiveness of disaster prevention systems) The present invention is a disaster prevention system that monitors for abnormalities by connecting terminal devices including fire hydrant devices to a disaster prevention receiving panel, and is equipped with an event detection unit that detects an operation event of a specified fire hydrant device provided in the fire hydrant device and transmits operation event information indicating the operation event, and an operation monitoring unit that, when operation event information that is a correct operation event of the fire hydrant device is received from the event detection unit, causes the fire hydrant device to output operation guidance that prompts the user to perform an operation for the next operation event after the operation event, and, when operation event information that is not a correct operation event of the fire hydrant device is received from the event detection unit, causes the fire hydrant device to output operation guidance that indicates an incorrect operation and that prompts the user to perform an operation for the correct operation event.Therefore, when the fire hydrant device is being operated in the correct procedure, the operation guidance that prompts the user to perform the next operation enables even road users who are unfamiliar with handling fire hydrant devices to quickly perform the correct operation in accordance with the specified order.

[0023] Furthermore, if the fire hydrant device is not operated in the correct procedure, an operation guide will be displayed informing the user of the incorrect operation and encouraging them to perform the correct operation, allowing the user to realize that they have performed an incorrect operation and to know the correct operation that should be performed, enabling them to properly recover from the incorrect operation and preventing unforeseen incidents from occurring.

[0024] (Effect of operation guidance control) The fire hydrant equipment includes a transmitter that issues a fire notification signal by transmitting a fire notification signal, a hydrant door that is opened when a fire hose stored inside the hydrant device is pulled out, a nozzle that is attached to the fire hose and detachably held in the nozzle holding part, and a hydrant valve opening / closing operation part that opens and closes a hydrant valve provided in a pipe that supplies fire water to the fire hose, and the operation monitoring part receives operation event information indicating an operation of the transmitter transmitted from the event detection part based on the fire notification signal transmitted from the transmitter, and, upon receiving operation event information indicating an opening operation of the hydrant door transmitted from the event detection part based on the opening of the hydrant door, outputs operation guidance to encourage the user to remove the nozzle, and, upon receiving operation event information other than operation event information indicating an opening operation of the hydrant door, outputs operation guidance to the effect that the operation is an error and to encourage the user to open the hydrant door, and, upon receiving operation event information indicating the operation of the transmitter and the opening operation of the hydrant door, outputs operation guidance to encourage the user to open the hydrant door When operation event information is received, operation guidance to open the fire hydrant valve opening / closing operation unit is output; when operation event information other than operation event information indicating the nozzle removal operation is received, operation guidance to the effect that the operation is incorrect and to urge the user to remove the nozzle is output; when operation event information indicating the operation of the transmitter, the opening operation of the hydrant door, and the removal operation of the nozzle is received, and operation event information indicating the opening operation of the fire hydrant valve opening / closing operation unit transmitted from the event detection unit based on the opening operation of the fire hydrant valve opening / closing operation unit is received, operation guidance to the effect that the fire hose is pulled out and water is discharged from the nozzle; and when operation event information other than operation event information indicating the opening operation of the hydrant valve opening / closing operation unit is received, operation guidance to the effect that the operation is incorrect and to urge the user to open the fire hydrant valve opening / closing operation unit is output.By following the operation guidance, road users can quickly use the fire hydrant device in the correct operating procedure, reporting a fire by the transmitter, opening the hydrant door, removing the nozzle, opening the hydrant valve opening / closing operation unit, and pulling out the hose.

[0025] Furthermore, if the fire hydrant device is not operated in the correct procedure, an operation guide will be displayed informing the user of the incorrect operation and encouraging them to perform the correct operation, allowing the user to realize that they have performed an incorrect operation and to know the correct operation that they should have performed, enabling them to properly recover from the incorrect operation and preventing unforeseen incidents from occurring.

[0026] (Effect of operation guidance control when a fire detector sends a fire signal) In addition, a fire detector is connected to the disaster prevention receiving panel as a terminal device, and when the disaster prevention receiving panel receives a fire signal transmitted by the fire detector upon detecting a fire, the operation monitoring unit outputs operation guidance to check for the fire at the fire hydrant device corresponding to the detection area of ​​the fire detector that transmitted the fire signal and to encourage the fire to be reported by operating a transmitter.Therefore, guidance on how to first check for the fire and operate a transmitter is output from the fire hydrant device that corresponds to the detection area of ​​the fire detector that detected the fire, for example, the fire hydrant device installed in a location close to the location of the fire, allowing road users to know which hydrant device to use and to quickly handle that hydrant device using the correct operating procedures.

[0027] (Effect of operation guidance control when a fire hydrant door is opened without a fire report) Furthermore, when the operation monitoring unit receives operation event information indicating the opening of the fire hydrant door without receiving operation event information indicating the operation of the transmitter, it outputs operation guidance to check for the fire and to encourage the user to report the fire by operating the transmitter.Therefore, in an urgent and chaotic situation such as a fire outbreak, it is expected that road users will first try to pull out the fire hose and open the fire hydrant door without reporting the fire by the transmitter, but in such a case, by issuing operation guidance to check for the fire and encourage the user to operate the transmitter to report the fire, it is possible to prevent a situation in which a fire is not reported.

[0028] (Effect of display and audio operation guidance) In addition, the fire hydrant device is provided with an operation guide display unit that displays a message urging the user to operate the device at positions corresponding to the transmitter, hydrant door, nozzle, and hydrant valve opening / closing operation unit, and is also provided with an audio output unit that outputs the operation guide by voice.When the operation monitoring unit outputs operation guide to urge the user to operate the device, it activates the corresponding operation guide display unit and causes the audio output unit to output a voice message of the corresponding operation guide.Therefore, the display and audio operation guide enable even road users who are unfamiliar with handling fire hydrant devices to reliably know where the transmitter, hydrant door, nozzle, or hydrant valve opening / closing operation unit are located on the fire hydrant device and which operating procedure should be used to operate it, and to handle the fire hydrant device correctly and quickly.

[0029] (Effect of fire hydrant devices) The present invention provides a fire hydrant device that is connected to a disaster prevention receiving panel and is equipped with an event detection unit that detects an operation event of a specific fire hydrant device provided in the fire hydrant device and transmits operation event information indicating the operation event, and an operation guidance unit that, if the operation event information transmitted by the event detection unit is a correct operation event of the fire hydrant device, outputs operation guidance based on predetermined control to encourage the user to perform an operation for the next operation event after the current operation event, and, if the operation event information transmitted by the event detection unit is not a correct operation event of the fire hydrant device, outputs operation guidance based on predetermined control to indicate that the operation is an incorrect operation and / or encourages the user to perform an operation for the correct operation event, thereby achieving the same effects as a disaster prevention system. Furthermore, the effects of other configurations of the fire hydrant device also achieve the same effects as the disaster prevention system described above. [Brief explanation of the drawings]

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a disaster prevention system and a fire hydrant device thereof according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0032] [Basic concept of the embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a disaster prevention system that connects terminal devices including a fire hydrant device to a disaster prevention receiving panel to monitor for abnormalities.

[0033] Here, a "fire hydrant device" is a type of emergency equipment used to build a disaster prevention system, which is installed in areas subject to fire extinguishing, such as tunnels on expressways and motorways. This includes devices that house fire hoses and fire extinguishers, as well as devices that are equipped with emergency notification devices such as red indicator lights and transmitters.

[0034] Furthermore, a "disaster prevention receiving panel" is installed in the electrical room of a facility or equipment that constructs a disaster prevention system, and monitors the area for abnormalities by connecting terminal devices of emergency equipment such as fire hydrants and fire detectors installed in the area. To monitor for abnormalities, for example, the terminal devices are connected via signal lines or transmission lines, and downstream signals containing control information are sent to the terminal devices to cause each terminal device to perform a specified operation, while upstream signals containing information on abnormalities detected from the terminal devices and information on the status of each terminal device are received to perform reception processing such as alarm processing and monitor the status of the terminal devices. Furthermore, there are two types of transmission between the disaster prevention receiving panel and the terminal devices: "R-type (Recorded-type) transmission," in which signals are sent and received by setting unique addresses to terminal devices including fire hydrants and fire detectors, and "P-type (Proprietary-type) transmission," in which signals are sent and received by connecting terminal devices on a line-by-line basis.

[0035] In addition, the "fire detector" included in the terminal device is a device that is installed in the area to be extinguished and detects fires that occur in the area to be extinguished.For example, if the area to be extinguished is inside a tunnel, it is installed at intervals of 25 meters or 50 meters along the length of the tunnel, has detection areas in both directions along the length of the tunnel, receives infrared energy in a wavelength band specific to the flame emitted from the source of the fire, detects the fire, and transmits a fire signal.

[0036] The "disaster prevention system" of the embodiment is characterized by including an event detection unit and an operation monitoring unit. In addition, the event detection unit and the operation monitoring unit may be provided at any location in the disaster prevention system, but includes, for example, a system in which the event detection unit is provided in a fire hydrant device and the operation monitoring unit is provided in a disaster prevention receiving panel.

[0037] Here, the "event detection unit" detects an operation event of a specific fire hydrant device provided in the hydrant device and transmits operation event information indicating the operation event, and the "operation monitoring unit" causes the hydrant device to output operation guidance encouraging the user to perform an operation for the next operation event after the operation event when it receives operation event information set as a correct operation event of the fire hydrant device from the event detection unit, and causes the hydrant device to output operation guidance indicating that the operation is incorrect and encouraging the user to perform an operation for the correct operation event when it receives operation event information that is not set as a correct operation event of the fire hydrant device from the event detection unit.

[0038] In addition, "a specified fire hydrant device installed in a fire hydrant system" refers to any fire hydrant device that detects its operation, and includes, for example, a transmitter, a fire hydrant door, a nozzle attached to a fire hose, and a fire hydrant valve opening / closing operating unit.

[0039] Here, a "transmitter" is a device that issues a fire alarm by sending a fire alarm signal via a push button or other means. A "hydrant door" is a device that opens when a fire hose stored inside the hydrant device is pulled out, and includes, for example, a device that is unlocked and opened by operating a door handle on the hydrant door. A "nozzle" is a nozzle that is attached to the fire hose and detachably held in the nozzle holder, serving as the nozzle tip from which fire water is sprayed. A "fire hydrant valve opening / closing operation unit" is a device that opens and closes a fire hydrant valve installed in a pipe that supplies fire water to the fire hose, and may be any structure that can open and close the fire hydrant valve to spray and stop water from the nozzle of the fire hose, including, for example, a fire hydrant valve opening / closing lever that can open and close the fire hydrant valve by operating the lever.

[0040] Furthermore, "detection of a fire hydrant device operation event" by the event detection unit includes not only detection of the operation of the fire hydrant device but also detection of an event caused by the operation of the fire hydrant device. For example, if the fire hydrant device is a transmitter, this does not mean detecting the operation of the transmitter by pressing a button or the like as an operation event, but also includes detecting "transmission of a fire alarm signal" as a result of the transmitter operation as an operation event of the transmitter.

[0041] Furthermore, the "operation event information" transmitted from the event detection unit is any information that can determine, distinguish, detect, etc. the operation event detected by the event detection unit based on the operation event information received by the operation monitoring unit that is the transmission destination, and includes, for example, bit information in which each operation event is listed as 1-bit information, and more specifically, includes information in which the bit information corresponding to an operation event is set to "0" when no operation event is detected, and set to "1" when an operation event is detected. Note that, as in the specific example where operation event information is listed as bit information, information on multiple operation events can be included in one piece of operation event information.

[0042] Furthermore, "operation event information that is a correct operation event of a fire hydrant device" refers to operation event information based on an operation event that occurs when a correct operation is performed as a correct operation procedure for operating a fire hydrant device, while "operation event information that is not a correct operation event of a fire hydrant device" refers to operation event information based on an operation event that occurs when an incorrect operation is performed as a correct operation procedure for operating a fire hydrant device. Here, the operation monitoring unit is free to determine what type of operation event information is a correct operation event, and this is set in consideration of the fire hydrant device provided in the fire hydrant device, the operation procedure for the fire hydrant device, the design philosophy of the designer, etc.

[0043] As a specific example, if the fire hydrant equipment includes a transmitter, a hydrant door, a nozzle, and a hydrant valve opening / closing operation unit, and the correct operating procedure for the fire hydrant device is to operate the transmitter, open the hydrant door, remove the nozzle, and open the hydrant valve opening / closing operation unit in that order, then the following four items fall under "operation event information that indicates the operation of the transmitter," "operation event information that indicates the operation of opening the hydrant door after receiving operation event information that indicates the operation of the transmitter," "operation event information that indicates the operation of removing the nozzle after receiving operation event information that indicates the operation of the transmitter and the opening operation of the hydrant door," and "operation event information that indicates the opening operation of the hydrant valve opening / closing operation unit after receiving operation event information that indicates the operation of the transmitter, the opening operation of the hydrant door, and the removal of the nozzle" are "operation event information that is a correct operation event for the fire hydrant equipment." In addition, other operation event information, such as "operation event information indicating the opening operation of a fire hydrant door without receiving operation event information indicating the operation of a transmitter," which is the case when a fire hydrant door is opened without a fire report being made, falls under "operation event information that is not a correct operation event of a fire hydrant device."

[0044] Furthermore, when the disaster prevention receiving panel receives a fire signal transmitted by a fire detector, the operation monitoring unit controls the fire hydrant device corresponding to the detection area of ​​the fire detector that transmitted the fire signal to output an operation guide urging the fire to check for a fire and to report the fire by operating a transmitter. Furthermore, the "fire hydrant device corresponding to the detection area of ​​the fire detector" includes, for example, a fire hydrant device installed within or near the detection area of ​​the fire detector, or in a position close to the location of the fire.

[0045] In addition, if the operation monitoring unit receives operation event information indicating the opening of the fire hydrant door without receiving operation event information indicating the operation of the transmitter, it controls the output of operation guidance urging the user to check for the fire and to report the fire by operating the transmitter.

[0046] In addition, the "fire hydrant device" of the embodiment is provided with an operation guide display unit that displays a prompt to operate at the positions corresponding to the transmitter, hydrant door, nozzle, and hydrant valve opening / closing operation unit as an operation guide unit for outputting operation guide, and is also provided with an audio output unit that outputs the operation guide by voice.

[0047] Furthermore, the "positions corresponding to the transmitter, hydrant door, nozzle, and hydrant valve opening / closing operation unit" where the operation guidance display unit is provided include, for example, the transmitter, hydrant door, nozzle, and hydrant valve opening / closing operation unit or positions in the vicinity of each of them. Furthermore, the "audio output unit" is arbitrary as long as it can convey operation guidance to road users by voice, and includes, for example, a speaker unit equipped with a speaker.

[0048] When the operation monitoring unit outputs operation guidance to the operation guidance display unit and the voice output unit to encourage operation, it activates the corresponding operation guidance display unit and outputs a voice message of the corresponding operation guidance from the voice output unit.

[0049] Specific embodiments will be described below. In the specific embodiments shown below, the "disaster prevention system" is "a tunnel disaster prevention system constructed in a tunnel of a motorway, which connects a fire hydrant device and a fire detector to a disaster prevention receiving panel and transmits and receives signals by R-type transmission", the "fire hydrant equipment" is "including a transmitter, a fire hydrant door, a nozzle, and a fire hydrant valve opening / closing lever", the "nozzle holding part" is "nozzle holder", the "correct operating procedure for the fire hydrant device" is "operating the transmitter, opening the fire hydrant door, taking out the nozzle, and opening the fire hydrant valve opening / closing operating part in this order", and the "event The "event detection unit" is "a terminal control device provided in the fire hydrant device, which has the function of detecting an operation event of the fire hydrant device and transmitting operation event information indicating the operation event," the "operation monitoring unit" is "realized by the control unit of the disaster prevention receiving panel," and the "operation guidance unit" is "a unit provided with a transmitter operation guidance display unit, a fire hydrant door door opening operation guidance display unit, a nozzle removal operation guidance display unit, and a valve opening / closing lever operation guidance display unit as operation guidance display units for the fire hydrant device, and a speaker unit as an audio output unit."

[0051] [a. Tunnel disaster prevention system] The tunnel disaster prevention system will be explained below. In this explanation, reference will be made to Figure 1 showing the tunnel disaster prevention system.

[0052] As shown in Figure 1, an inbound tunnel 1 and an outbound tunnel 2 have been constructed as tunnels for expressways, and the inbound tunnel 1 and the outbound tunnel 2 are connected by an evacuation tunnel 3. Inside the inbound tunnel 1 and the outbound tunnel 2, fire detectors 16 are installed along the longitudinal walls of the tunnel, for example, at intervals of 50 meters. The fire detectors 16 set a detection area of ​​50 meters on both sides of the longitudinal direction of the tunnel, and detect fires by receiving infrared energy emitted from flames caused by fires, etc. Furthermore, each fire detector 16 is assigned a unique address corresponding to the R-type transmission method.

[0053] Furthermore, inside the inbound tunnel 1 and the outbound tunnel 2, fire hydrant devices 20 are embedded and installed, for example, at intervals of 50 meters along the walls of the watchman passages that are provided along the longitudinal direction of the tunnels. The details of the fire hydrant devices 20 will be described separately later.

[0054] In addition, a disaster prevention receiving panel 10 is installed in the electrical room of the tunnel facilities to connect terminal devices such as fire detectors 16 and fire hydrant devices 20 installed in the tunnel and monitor abnormalities, including fires, inside the tunnel. Details of the disaster prevention receiving panel 10 will be described separately later.

[0055] Furthermore, in order to connect the disaster prevention receiving panel 10 to each terminal device, a transmission cable 12 including transmission lines 1210, 1220, 1230, and 1240 is drawn out from the disaster prevention receiving panel 10. The transmission lines 1210 and 1220 are drawn out into the up-line tunnel 1, and the transmission lines 1230 and 1240 are drawn out into the down-line tunnel 2. A fire detector 16 is connected to the transmission lines 1210 and 1230, and a fire hydrant device 20 is connected to the transmission lines 1220 and 1240.

[0056] In addition, transmission lines 1210 to 1240 are wired via a relay amplifier panel 18 installed inside the tunnel, and the relay amplifier panel 18 relays and amplifies signals sent and received between the fire detector 16 and the fire hydrant device 20 installed far from the disaster prevention receiving panel 10 and the disaster prevention receiving panel 10.

[0057] The transmission lines 1210-1240 may be configured arbitrarily, but may be configured, for example, with a power line, a common line, and a transmission line for transmitting downstream signals in voltage mode from the disaster prevention receiving panel 10 to the terminal equipment and upstream signals in current mode from the terminal equipment to the disaster prevention receiving panel 10. When transmitting downstream signals in voltage mode, the downstream signals are transmitted as voltage pulses that change the line voltage between 18 volts and 30 volts, for example. When transmitting upstream signals in current mode, the upstream signals are transmitted as a current pulse train, with a signal current flowing at the timing of bit 1 of the transmission data, for example. In the case of transmission over two-wire transmission lines 1210-1240 consisting of a transmission line and a common line, half-duplex communication is achieved, in which downstream signals in voltage mode and upstream signals in current mode are transmitted by switching between them.

[0058] Other emergency tunnel equipment includes a fire pump system 24, an IG satellite station system (intelligent satellite station system) 26, ventilation equipment 28, warning display board system 30, radio rebroadcasting equipment 32, television monitoring equipment 34, and lighting equipment 36, and these systems are individually connected to the disaster prevention receiving panel 10 by P-type signal lines 14, except that the IG satellite station system 26 is connected to the disaster prevention receiving panel 10 by a data transmission line. Note that there are also cases where transmission between the fire pump system 24 and the disaster prevention receiving panel 10 is R-type transmission, and the fire pump system 24 and the disaster prevention receiving panel 10 are connected by an R-type transmission line.

[0059] The IG satellite station equipment 26 is a communications system connecting the equipment installed inside the tunnel, including the disaster prevention receiving panel 10, with remote management equipment installed far outside the tunnel. The ventilation system 28 energizes the air inside the tunnel by blowing out high-speed air from jet fans installed on the ceiling, creating a longitudinal ventilation flow. The warning display board equipment 30 notifies road users of abnormalities inside the tunnel by displaying them on an electronic display board. The radio rebroadcasting equipment 32 allows road users and others inside the tunnel to receive information from the road administrator. The television monitoring equipment 34 is used to confirm the size and location of a fire, activate water spray equipment, and monitor the situation inside the tunnel, for example, to guide evacuation. The lighting equipment 36 powers the lighting equipment inside the tunnel.

[0060] [b. Fire hydrant equipment] Next, the fire hydrant device will be described with reference to Fig. 2, which shows the fire hydrant device, Fig. 3, which shows the internal structure of the fire hydrant device from the front with the hydrant door, maintenance door, and fire extinguisher door in the open state, and Fig. 4, which shows the configuration of the terminal control device provided in the fire hydrant device.

[0061] 2 and 3, the X, Y, and Z directions are perpendicular to each other. Specifically, when looking at the front of the fire hydrant device equipped with various doors, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-to-back direction. The +X side of the X direction is the right side, the -X side is the left side, the +Y side of the Y direction is the top side, the -Y side is the bottom side, and the +Z side of the Z direction is the front side, and the -Z side is the back side. The Z direction is not shown in FIGS. 2 and 3.

[0062] (b1. Structure of fire hydrant equipment) First, the structure of the fire hydrant device will be described. As shown in Figure 2, the fire hydrant device 20 is divided into a housing 60 whose interior serves as a fire hydrant storage section and a housing 62 whose interior serves as a fire extinguisher storage section, and decorative frames 64, 66 are attached to the front of the housings 60, 62.

[0063] The door opening of the decorative frame 64 of the housing 60 is divided into upper and lower halves, with a forward-tilting fire hydrant door 70 that opens downwards on a hinge provided at the lower part of the door opening, and a maintenance door 68 that opens upwards on a hinge provided at the upper part of the door opening, with a hydrant storage compartment inside which stores fire hoses and valves including a hydrant valve as fire hydrant equipment. The fire hydrant door 70 is provided with a door handle 72, and when a road user reaches into the door handle 72 and pulls it towards them, the lock is released and the fire hydrant door 70 can be opened. The fire hydrant door 70 is treated as being included in the fire hydrant equipment.

[0064] Also, a door detection switch 74 is provided, for example, on the left side of the door opening of the hydrant door 70. The door detection switch 74 is a switch that is activated when a road user pulls the door handle 72 toward themselves to open the hydrant door 70, and may have any structure or type, but may be, for example, a limit switch equipped with a switch knob or switch lever that appears and disappears in response to the opening and closing operation of the hydrant door 70. In this embodiment, the door detection switch 74 is turned off when the hydrant door 70 is closed, and turned on when the hydrant door 70 is open.

[0065] The door handle 72 is also provided with a door opening operation guide display unit 76. The structure and function of the door opening operation guide display unit 76 are arbitrary, but for example, it is a light-emitting plate member using an LED as a light source, and is arranged surrounding the periphery of the door handle 72. Based on instruction information included in the control command signal from the disaster prevention receiving panel 10, the light-emitting plate member flashes to display a guide that urges the user to open the fire hydrant door 70.

[0066] Furthermore, a fire extinguisher door 78 that opens sideways to the left on a hinge is provided on the left side of the door opening in the decorative frame 11b of the housing 10b, and the fire extinguisher storage section inside can store, for example, two fire extinguishers. The fire extinguisher door 78 is provided with a door handle 80, and when a road user reaches into the door handle 80 and pulls it toward them, the lock is released and the fire extinguisher door 78 can be opened. In addition, a viewing window 82 is provided below the fire extinguisher door 78, making it possible to check from the outside whether a fire extinguisher is present.

[0067] An electrical door 84 that opens sideways to the right on a hinge is provided on the right side of the door opening of the decorative frame 11b. The electrical door 84 is provided with electrical equipment such as a red indicator light 86, a transmitter 88, and an answer lamp 90, and a telephone jack is provided inside the housing 62 of the electrical door 84. The red indicator light 22, transmitter 24, answer lamp 26, and telephone jack provided on the electrical door 20 constitute an emergency notification device, and the transmitter 88 is treated as being included in the fire hydrant equipment.

[0068] The red indicator light 86 is always lit, allowing the location of the fire hydrant device 20 to be known from a distance. In the event of a fire, when the transmitter 88 is pressed and the push button switch is turned on, a fire notification signal is sent, and a fire alarm is output from the disaster prevention receiving panel 10 based on the fire notification signal. In response to this, a response signal is sent from the disaster prevention receiving panel 10 to the fire hydrant device 20 side by R-type transmission control, causing the red indicator light 86 to flash and the response lamp 90 to light up.

[0069] The transmitter 88 is also provided with a transmitter operation guide display unit 96. The structure and function of the transmitter operation guide display unit 96 are arbitrary, but for example, like the door opening operation guide display unit 76, it is a light-emitting plate member with an LED as a light source, and is arranged surrounding the periphery of the transmitter 88. Based on instruction information included in the control command signal from the disaster prevention receiving panel 10, the light-emitting plate member flashes to display a guide that encourages the user to press the button on the transmitter 88.

[0070] A speaker unit 98 is provided below the electrical door 84. Based on instruction information contained in the control command signal from the disaster prevention receiving panel 10, the speaker unit 98 outputs a predetermined voice message urging the operation of the fire hydrant equipment, including the operation of the push button on the transmitter 88, the opening operation of the fire hydrant door 70, the removal operation of the nozzle, and the opening operation of the fire hydrant valve opening / closing lever, or pointing out an incorrect operation of the fire hydrant equipment.

[0071] (b2. Internal structure of fire hydrant equipment) Next, we will explain the internal structure of the fire hydrant device 20 shown in Figure 2. As shown in Figure 3, the inside of the housing 60 that serves as the fire hydrant storage section 100 is divided into a valve storage section 102 and a hose storage section 104.

[0072] A water supply faucet 108 is connected to a water supply pipe 106 drawn in from the outside in the valve storage section 102, and the water supply pipe 106 branches downward and is connected to a fire hose 114 via a fire hydrant valve 110 and an automatic pressure regulating valve 112.

[0073] The hose storage section 104 is provided with a hose storage frame 116, in which a fire hose 114 is pulled in from below and wound inward clockwise or counterclockwise to store it. A nozzle 120 is attached to the tip of the fire hose 114 pulled out through a hose guide 118 installed on the back side of the fire hydrant door 70, and the nozzle 120 is held detachably in a nozzle holder 122.

[0074] The fire hydrant valve 110 is opened and closed by a fire hydrant valve opening / closing lever 124 provided on an operation box 125 installed on the back side of the hydrant door 70, and the fire hydrant valve 110 is opened and closed in conjunction with the opening and closing operation of the fire hydrant valve opening / closing lever 124 by a known wire link mechanism provided between the operation box 125 and an interlocking box 126 provided on the fire hydrant valve 110 corresponding to the operation box 125.

[0075] In addition, a pump start interlock switch 130 is provided in the interlock box 126, which is turned on and off in response to the opening and closing of the fire hydrant valve 110 and sends a pump start signal when turned on, and a pump start switch 128 is provided on the upper right of the hydrant 108, which is used by the fire brigade and sends a pump start signal when turned on.

[0076] The operation box 125 is also provided with a valve opening / closing lever detection switch 136. The valve opening / closing lever detection switch 136 is a switch that is activated when a road user operates the fire hydrant valve opening / closing lever 124 from the closed position to the open position, and may have any structure or type, but for example, a limit switch is used, similar to the door detection switch 74. In this embodiment, the valve opening / closing lever detection switch 136 is turned off when the fire hydrant valve opening / closing lever 124 is in the closed position shown in the figure, and is turned on when the fire hydrant valve opening / closing lever 124 moves away from the closed position.

[0077] Furthermore, the operating handle of the fire hydrant valve opening / closing lever 124 is provided with a valve opening / closing lever operation guide display unit 138. The structure and function of the valve opening / closing lever operation guide display unit 138 are arbitrary, but for example, a light-emitting cylinder member with an LED as a light source is provided at the right end of the operating handle, and based on the instruction information included in the control command signal from the disaster prevention receiving panel 10, the light-emitting cylinder member flashes to display a guide message urging the user to open the fire hydrant valve opening / closing lever 124.

[0078] The nozzle holder 122 is also provided with a nozzle detection switch 132. The nozzle detection switch 132 is a switch that is activated when a road user removes the nozzle 120 from the nozzle holder 122, and may have any structure or type, but for example, a limit switch is used, similar to the door detection switch 74. In this embodiment, the nozzle detection switch 132 is turned off when the nozzle 120 is held in the nozzle holder 122, and turned on when the nozzle 120 is removed from the nozzle holder 122.

[0079] The nozzle holder 122 is also provided with a nozzle removal operation guide display unit 134. The structure and function of the nozzle removal operation guide display unit 134 are arbitrary, but for example, like the door opening operation guide display unit 76, it is a light-emitting plate member with an LED as a light source, and is arranged surrounding the periphery of the nozzle holder 122. Based on instruction information included in the control command signal from the disaster prevention receiving panel 10, the light-emitting plate member flashes to display a guide message urging the user to remove the nozzle 120.

[0080] Additionally, an operation method nameplate 144 is disposed behind (inside the housing) the nozzle holder 122. The operation method nameplate 144 is divided into three frames and graphically displays the procedures for removing the nozzle, opening the fire hydrant valve opening / closing lever, and discharging water from the nozzle of the fire hose.

[0081] Furthermore, the interior of the housing 62 (on the fire extinguisher door 78 side) is a fire extinguisher storage section 65, which stores two fire extinguishers 140. Terminal boxes 92, 94 are installed on the rear surface of the fire extinguisher storage section 65. A red indicator light 86 provided on the electrical door 84 is connected to the terminal box 92 via a wiring cable, and a transmitter 88, an answer lamp 90, a telephone jack and speaker section 98 provided on the electrical door 84, and a pump start switch 128 and a pump start interlock switch 130 provided in the valve storage section 102 are connected to the terminal box 94 via wiring cables.

[0082] A cable rack 142 is also installed in the upper part of the housing 60, extending from near the center of the valve storage section 102 to the hydrant storage section 104. High-voltage cables are inserted through the cable rack 142 to connect high-voltage cables drawn into the valve storage section 102 from the outside to the terminal box 92, low-voltage cables are inserted through the cable rack 142 to connect low-voltage cables drawn into the valve storage section 102 from the outside to the terminal box 94, and further wiring cables are inserted through the cable rack 142 to connect wiring cables from the pump start switch 128 and the pump start interlock switch 130 to the terminal box 94.

[0083] Furthermore, a terminal control device 58 is installed below the terminal boxes 92, 94 on the rear surface of the fire extinguisher storage section 65. The terminal control device 58 is the point where transmission lines 1220, 1240 drawn out from the disaster prevention receiving panel 10 are connected, and transmits and receives signals using R-type transmission control between the terminal control device 58 and the disaster prevention receiving panel 10. Details of the terminal control device 58 will be described separately later. Furthermore, the wiring required for control by the terminal control device 58 may be routed by passing it through the cable rack 142.

[0084] (b3. Terminal control device) Next, the terminal control device provided in the fire hydrant device will be described. As shown in Fig. 4, the terminal control device 58 is provided with a transmission unit 148 and a control unit 150.

[0085] The transmitter 148 transmits and receives signals to and from the disaster prevention receiving panel 10 using R-type transmission control. The control unit 150 is a computer circuit equipped with a CPU, memory, various input / output ports, etc., and functions such as transmission control of operation event information, operation control of electrical equipment based on instruction information from the disaster prevention receiving panel 10, and output control of operation guidance are realized by the CPU executing a program. In addition, a unique address is preset for the transmitter 148 in order to transmit and receive signals to and from the disaster prevention receiving panel 10 using R-type transmission control.

[0086] Furthermore, a transmitter 88 and a response lamp 90 are connected to the control unit 150 as an emergency notification unit 152 that is operated and activated when reporting, and a pump start switch 128 and a pump start interlock switch 130 are connected to the control unit 150 as a pump equipment start unit 153 that is operated when starting the pump equipment. Note that the pump start switch 128 and the pump start interlock switch 130 may be connected in parallel, and the input system to the control unit 150 may be a single system.

[0087] In addition, the control unit 150 is connected to the door detection switch 74, the nozzle detection switch 132, and the valve opening / closing lever detection switch 136 as an operation event detection unit 154 that detects operation events of the hydrant equipment operated when handling the hydrant device, and further connected to the door opening operation guide display unit 76, the transmitter operation guide display unit 96, the nozzle removal operation guide display unit 134, the valve opening / closing lever operation guide display unit 136, and the speaker unit 98 as an operation guide unit 156 that outputs operation guide for the hydrant equipment.

[0088] The control unit 150 detects an operation event of the fire hydrant equipment based on a fire notification signal from the transmitter 88, a pump start signal from the pump start switch 128 or the pump start interlock switch 130, or an ON signal based on the ON of any of the door detection switch 74, the nozzle detection switch 132, and the valve opening / closing lever detection switch 136, and causes the transmission unit 148 to transmit a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the operation event detected by R-type transmission control.

[0089] Furthermore, when the control unit 150 receives a control command signal (downstream signal) including predetermined instruction information from the disaster prevention receiving panel 10 at the transmission unit 148, it performs control to activate the response lamp 90, the door open operation guide display unit 76, the transmitter operation guide display unit 96, the nozzle removal operation guide display unit 134, the valve opening / closing lever operation guide display unit 136, or the speaker unit 98, based on the instruction information included in the control command signal. Details of the R-type transmission control performed with the disaster prevention receiving panel 10 will be described separately later.

[0090] [c. Disaster prevention receiving panel] Next, the disaster prevention receiving panel will be explained with reference to Fig. 5 showing the configuration of the disaster prevention receiving panel.

[0091] (c1. Configuration of the disaster prevention receiving panel) 5, the disaster prevention receiving panel 10 includes a control unit 40, which is further provided with transmission units 4210 to 4240, an alarm unit 45, a display unit 46, an operation unit 48, a modem 50, and a P-type transmission unit 52. The function of the operation monitoring unit is realized by the control unit 40.

[0092] The control unit 40 is a computer circuit or the like equipped with a CPU, memory, various input / output ports, etc., and functions such as abnormality monitoring control, alarm control, operation monitoring control, and instruction information transmission control are realized by the CPU executing a program.

[0093] In addition, transmission lines 1210 to 1240 are drawn out from the transmission units 4210 to 4240 in correspondence with the fire detectors 16 or fire hydrant devices 20 installed in each of the up-track tunnel 1 and the down-track tunnel 2, the alarm unit 45 is equipped with speakers and alarm indicator lights, the display unit 46 is equipped with an LCD display, etc., the operation unit 48 is equipped with various switches, a data transmission line is drawn out from the modem 50 to connect the IG substation equipment 26, and furthermore, individual P-type signal lines 14 are drawn out from the P-type transmission unit 52 to connect the ventilation equipment 28, the alarm display board equipment 30, the radio rebroadcasting equipment 32, the television monitoring equipment 34, the lighting equipment 36 and the fire pump equipment 24.

[0094] (c2. R-type transmission control between fire detectors) Next, we will explain the R-type transmission control performed between the fire detector and the disaster prevention receiving panel 10. The transmitters 4210 and 4230 of the disaster prevention receiving panel 10 connected to the fire detector 16 perform R-type transmission control in which signals are sent and received according to a predetermined communication protocol, allowing the disaster prevention receiving panel 10 to detect the status of each fire detector 16 individually and to centrally monitor the fire detector 16 that has detected a fire.

[0095] As for the R-type transmission control performed between the fire detector 16, in the normal monitoring state, the transmission unit 4210 of the disaster prevention receiving panel 10 transmits a polling command signal (downstream signal) in voltage mode at a predetermined timing, for example, every minute, which sequentially specifies the addresses of the fire detectors 16 connected to the transmission line 1210, and receives a response signal (upstream signal) transmitted in current mode from the fire detector 16, thereby the disaster prevention receiving panel 10 detects the status of the fire detector 16.

[0096] When a fire detector 16 receives infrared energy radiated from a flame of a fire or the like and detects a fire, the fire detector 16 that detected the fire transmits an interrupt signal as a fire signal to the connected transmission line 1210. When the transmission unit 4210 of the disaster prevention receiving panel 10 receives the interrupt signal from the fire detector 16 that detected the fire, it transmits a group search command signal to the fire detector 16 to identify the group that detected the fire, then transmits an intra-group search command signal to the fire detectors 16 of the identified group to search for the address of the fire detector 16 that detected the fire, thereby identifying the fire detector 16 that detected the fire, and designating the address of the identified fire detector 16 to transmit a polling command signal at a shorter cycle than the cycle in the normal monitoring state to receive a response signal from the fire detector 16 that detected the fire, thereby intensively monitoring the fire detector 16 that detected the fire.

[0097] Here, the interrupt signal is a signal that is sent with priority from the fire detector 16 that detected a fire to the disaster prevention receiving panel 10, regardless of the transmission status of the downlink signal or the uplink signal, and the format of the interrupt signal is arbitrary, but for example, a signal in which the bit information of the uplink signal sent in current mode is all 1 (constant current signal) is used. In addition, the transmission unit 4230 of the disaster prevention receiving panel 10 connected to the fire detector 16 in the downlink tunnel 2 also has a similar R-type transmission control.

[0098] (c3. R-type transmission control between the fire hydrant device) Next, we will explain the R-type transmission control performed between the fire hydrant devices. By performing R-type transmission control in which the transmitters 4220, 4240 of the disaster prevention receiving panel 10 connected to the fire hydrant device 20 send and receive signals according to a predetermined communication protocol, the disaster prevention receiving panel 10 individually detects and monitors the status of the fire hydrant device 20 and operation events performed by the fire hydrant device 20, and sends instruction information to control the operation of the electrical equipment of the fire hydrant device 20 and the output of operation guidance, etc.

[0099] As shown in Figure 3, the fire hydrant device 20 is provided with a terminal control device 58 equipped with a transmission unit 148 and a control unit 150, and the transmission unit 148 of the terminal control device 58 receives polling command signals or control command signals, which are downstream signals transmitted in voltage mode from the transmission units 4220 and 4240 of the disaster prevention receiving panel 10, and transmits response signals and interrupt signals, which are upstream signals, to the transmission units 4220 and 4230 of the disaster prevention receiving panel 10 in current mode.

[0100] In the normal monitoring state, R-type transmission control is performed between the fire hydrant device 20 and the disaster prevention receiving panel 10, and the transmission unit 4220 of the disaster prevention receiving panel 10 transmits polling command signals (downstream signals) sequentially specifying the addresses of the fire hydrant devices 20 connected to the transmission line 1220 at a predetermined timing, for example, every minute. When the transmission unit 148 of the terminal control device 58 provided in the fire hydrant device 20 receives a polling command signal specifying its own address, it outputs a signal notifying the control unit 150 that the polling command signal has been received, and transmits a response signal (upstream signal) including response information instructed by the control unit 150 to the disaster prevention receiving panel 10 at the response timing following the reception of the polling command signal. The response information in the normal monitoring state is arbitrary, and may be, for example, status information indicating that the fire hydrant device 20 is in a normal state.

[0101] In addition, when the terminal control device 58 provided in the fire hydrant device 20 detects the input of an on signal of the push button switch by operating the push button of the transmitter 88, i.e., the input of a fire notification signal, or detects the opening operation of the fire hydrant door 70, and if an interrupt signal has not yet been sent, the transmission unit 148 performs transmission control to send an interrupt signal to the disaster prevention receiving panel 10 at the instruction of the control unit 150.

[0102] In this case, the transmission control on the disaster prevention receiving panel 10 side is the same as when the fire detector 16 detects a fire and transmits an interrupt signal as a fire signal to the disaster prevention receiving panel 10. When the transmission unit 4220 of the disaster prevention receiving panel 10 receives an interrupt signal from the fire hydrant device 20, it transmits a group search command signal to the fire hydrant device 20 to identify the group of fire hydrant devices 20 that transmitted the interrupt signal, i.e., the group of fire hydrant devices 20 for which a fire report or the opening operation of the fire hydrant door 70 was performed without a fire report was made, and then it transmits an intra-group search command signal to the fire hydrant devices 20 of the identified group to search for the address of the fire hydrant device 20 that transmitted the interrupt signal, thereby identifying the fire hydrant device 20 that transmitted the interrupt signal, and then it specifies the address of the identified fire hydrant device 20 and transmits a polling command signal at a shorter period than the period in the normal monitoring state to receive a response signal from the fire hydrant device 20 that transmitted the interrupt signal, thereby intensively monitoring the fire hydrant device 20 that transmitted the interrupt signal.

[0103] Furthermore, as a transmission control after the disaster prevention receiving panel 10 has identified the hydrant device 20, when the transmission unit 148 of the terminal control device 58 provided in the hydrant device 20 receives a polling command signal specifying its own address, it outputs a signal notifying the control unit 150 that it has received the polling command signal, and the control unit 150 detects the on / off states (operation events) of the pump start switch 128, pump start interlocking switch 130, door detection switch 74, nozzle detection switch 132, and valve opening / closing lever detection switch 136 at that time, and transmits a response signal (upstream signal) including switch operation information indicating the operation of each switch as operation event information to the disaster prevention receiving panel 10 in accordance with instructions from the control unit 150 at the response timing following the reception of the polling command signal. Note that the switch operation information included in the response signal is one type of response information included in the response signal.

[0104] Here, the "switch operation information" is any information that can detect the on / off state (operation event) of each switch on the disaster prevention receiving panel 10 side, and may be, for example, 6-bit information that corresponds to six lines of the transmitter 88, pump start switch 128, pump start interlocking switch 130, door detection switch 74, nozzle detection switch 132, and valve opening / closing lever detection switch 136 that are input and connected to the control unit 150, with bit 1 set when the switch is in the on state and bit 0 when the switch is in the off state. In the following explanation, the first bit of the 6-bit information corresponds to the transmitter 88, the second bit to the pump start switch 128, the third bit to the pump start interlocking switch 130, the fourth bit to the door detection switch 74, the fifth bit to the nozzle detection switch 132, and the last bit to the valve opening / closing lever detection switch 136.

[0105] The disaster prevention receiving panel 10 then detects the on / off state (operation event) of the transmitter 88 from the first bit of information in the switch operation information included in the response signal received by the transmission unit 4220 of the disaster prevention receiving panel 10. The disaster prevention receiving panel 10 also detects the on / off state (operation event) of the pump start switch 128 or the pump start-up interlock switch 130 from the second and third two bits from the beginning of the switch operation information, and if the bit information corresponding to either the pump start switch 128 or the pump start-up interlock switch 130 is bit 1, the control unit 40 of the disaster prevention receiving panel 10 controls the fire pump equipment 24 to start the pump.

[0106] In addition, the on / off states (operation events) of the door detection switch 74, nozzle detection switch 132, and valve opening / closing lever detection switch 136 are detected from the 3 bits of information from the fourth to sixth from the beginning of the switch operation information, and if the bit information corresponding to the door detection switch 74 is bit 1, the control unit 40 of the disaster prevention receiving panel 10 detects the opening operation of the fire hydrant door 70, and if the bit information corresponding to the nozzle detection switch 132 is bit 1, the control unit 40 of the disaster prevention receiving panel 10 detects the removal operation of the nozzle 120, and furthermore, if the bit information corresponding to the valve opening / closing lever detection switch 136 is bit 1, the control unit 40 of the disaster prevention receiving panel 10 detects the opening operation of the fire hydrant valve opening / closing lever 124.

[0107] The disaster prevention receiving panel 10 controls the fire hydrant device 20 to output operation guidance in response to the detected operation event, the details of which will be described later. The transmission unit 4240 connected to the fire hydrant device 20 in the down-link tunnel 2 also has the same R-type transmission control.

[0108] [d. Operation guidance control of fire hydrant equipment] Next, we will explain the operation guidance control of the fire hydrant device based on the cooperation between the fire hydrant device and the disaster prevention receiving panel. In the following explanation, the operation guidance control will be divided into operation guidance control when the operation of the transmitter is first detected, operation guidance control when the fire detector fire signal is first received, and operation guidance control when the opening operation of the fire hydrant door is first detected.

[0109] [e. Operation guidance control based on the fire alarm signal from the transmitter] First, the operation guidance control when the disaster prevention receiving panel first detects the operation of the transmitter will be described.

[0110] (e1. Operation guidance control to encourage opening of fire hydrant doors) The control unit 40 of the disaster prevention receiving panel 10 receives an interrupt signal from the terminal control device 58 of the fire hydrant device 20 by the transmission units 4220, 4240 operating the push button of the transmitter 88 provided in the fire hydrant device 20, and identifies the address of the fire hydrant device 20 that sent the interrupt signal. Furthermore, the control unit 40 detects a fire report from the operation event information indicating the operation of the transmitter included in the response signal received from the identified fire hydrant device 20 and the interrupt signal that has already been received, separately detects a fire, and determines that it is a fire by combining this with the fire detection by the interrupt signal sent as a fire signal from the fire detector 16, and causes the alarm unit 45 to output a fire alarm, and also controls the alarm display board equipment 30 to display a message such as "No entry into tunnel," and causes the transmission units 4220, 4240 to transmit a control command signal including instruction information for guiding the opening of the fire hydrant door 70 to the identified fire hydrant device 20.

[0111] The terminal control device 58 of the fire hydrant device 20, which has received a control command signal including instruction information for door opening operation guidance with its own address specified from the disaster prevention receiving panel 10, causes the control unit 150 to flash the door opening operation guidance display unit 76 as operation guidance to encourage the user to open the hydrant door 70, and also causes the speaker unit 98 to output a predetermined voice message such as "Beep, beep, please pull the door handle to open the hydrant door." The voice data for the voice message to be output from the speaker unit 98 is either stored in advance in the memory of the terminal control device 58, or is output by transmitting the voice data from the disaster prevention receiving panel 10. This also applies to the output of other voice messages for operation guidance.

[0112] When a road user operates the fire hydrant door 70 based on this operation guidance, the door detection switch 74 turns on, and the terminal control device 58, at the response timing following reception of a polling command signal specifying its own address, transmits a response signal to the disaster prevention receiving panel 10, which includes operation event information indicating the operation of the transmitter and the opening operation of the fire hydrant door, i.e., switch operation information with the first and fourth bit information from the beginning set to bit 1.

[0113] Furthermore, since the response lamp 90 provided on the fire hydrant device 20 lights up as a confirmation response from the disaster prevention receiving panel 10 to the fire report from the transmitter 88, the control command signal transmitted from the disaster prevention receiving panel 10 also includes instruction information to turn on the response lamp 90, and the terminal control device 58 of the fire hydrant device 20, which has received the control command signal including instruction information for the response lamp 90, turns on the response lamp 90 by means of the control unit 150. Note that the instruction information for turning on the response lamp 90 and the instruction information for guiding the door opening operation may be included in the same control command signal, or may be included in separate control command signals.

[0114] (e2. Operation guidance control to encourage nozzle removal operation) Next, when the control unit 40 of the disaster prevention receiving panel 10 receives a response signal from the fire hydrant device 20 including operation event information indicating the operation of the transmitter and the opening operation of the hydrant door, it specifies the address of the identified fire hydrant device 20 and causes the transmission units 4220, 4240 to transmit a control command signal including instruction information for guiding the nozzle removal operation.

[0115] The terminal control device 58 of the fire hydrant device 20, which has received a control command signal including instruction information for nozzle removal operation guidance with its own address specified from the disaster prevention receiving panel 10, causes the control unit 150 to flash the nozzle removal operation guidance display unit 134 as operation guidance to encourage the removal operation of the nozzle 120, and also outputs a predetermined voice message from the speaker unit 98, such as "Beep beep, please remove the nozzle from the nozzle holder and pull out the hose."

[0116] When a road user removes the nozzle 120 from the nozzle holder 122 based on this operation guidance, the nozzle detection switch 132 turns on, and the terminal control device 58, at the response timing following reception of a polling command signal specifying its own address, transmits a response signal to the disaster prevention receiving panel 10, which includes operation event information indicating the operation of the transmitter, the opening operation of the fire hydrant door, and the operation of removing the nozzle, i.e., switch operation information with the first and fourth and fifth bit information from the top set to bit 1.

[0117] (e3. Operation guidance control to encourage opening of fire hydrant valve opening / closing lever) Next, when the control unit 40 of the disaster prevention receiving panel 10 receives a response signal from the fire hydrant device 20 that includes operation event information indicating the operation of the transmitter, the opening operation of the hydrant door, and the nozzle removal operation, it specifies the address of the identified fire hydrant device 20 and causes the transmission units 4220, 4240 to transmit a control command signal that includes instruction information for guiding the opening operation of the fire hydrant valve opening / closing lever.

[0118] The terminal control device 58 of the fire hydrant device 20, which has received a control command signal including instruction information for guidance on opening the fire hydrant valve opening / closing lever for which its own address has been designated from the disaster prevention receiving panel 10, causes the control unit 150 to flash the valve opening / closing lever operation guidance display unit 138 as operation guidance to encourage the opening of the fire hydrant valve opening / closing lever 124, and also outputs a predetermined voice message from the speaker unit 98, such as "Beep beep, please open the fire hydrant valve opening / closing lever. Water will now begin to be discharged. Please hold the nozzle firmly."

[0119] When a road user opens the fire hydrant valve opening / closing lever 124 based on this operation guidance, the valve opening / closing lever detection switch 136 turns on, and the terminal control device 58, at the response timing following reception of a polling command signal specifying its own address, transmits a response signal to the disaster prevention receiving panel 10, which includes operation event information indicating the operation of the transmitter, the opening operation of the fire hydrant door, the removal operation of the nozzle, and the opening operation of the fire hydrant valve opening / closing lever, i.e., switch operation information in which the first and fourth to sixth bit information from the top is set to bit 1.

[0120] Then, the disaster prevention receiving panel 10, which receives a response signal including operation event information indicating the opening operation of the fire hydrant door, the removal operation of the nozzle, and the opening operation of the fire hydrant valve opening / closing lever, specifies the address of the fire hydrant device 20 identified by the control unit 40 and causes the transmission units 4220, 4240 to transmit a control command signal including instruction information for water discharge operation guidance.

[0121] The terminal control device 58 of the fire hydrant device 20, which receives a control command signal including instruction information for water discharge operation guidance with its own address specified from the disaster prevention receiving panel 10, causes the control unit 150 to output, for example, from the speaker unit 98, a predetermined voice message such as "Point the nozzle at the fire location and pull out the hose while spraying water. Please spray water from a position sufficiently far away from the fire location."

[0122] (e4. Operational guidance for incorrect operation) Here, if a road user mistakenly opens the hydrant valve opening / closing lever 124 without removing the nozzle 120, despite the hydrant device 20 outputting an operation guide urging the user to remove the nozzle, the valve opening / closing lever detection switch 136 will be turned on, and the terminal control device 58 will transmit a response signal to the disaster prevention receiving panel 10 at the response timing following receipt of a polling command signal specifying its own address, which response signal includes operation event information indicating the operation of the transmitter, the opening operation of the hydrant door, and the opening operation of the hydrant valve opening / closing lever, i.e., switch operation information with the first and fourth and sixth bit information from the beginning set to bit 1.

[0123] However, the opening operation of the fire hydrant valve opening / closing lever 124 performed by the road user following the opening operation of the hydrant door 70 is an erroneous operation that differs from the correct operating procedure for the fire hydrant device, and the disaster prevention receiving panel 10 does not receive a response signal including operation event information indicating a nozzle removal operation, i.e., a response signal including switch operation information with the fifth bit information from the beginning set to bit 1, but instead receives a response signal including operation event information indicating an opening operation of the fire hydrant valve opening / closing lever 120, i.e., a response signal including switch operation information with the sixth bit information from the beginning set to bit 1.Therefore, the control unit 40 of the disaster prevention receiving panel 10 can detect that the opening operation of the fire hydrant valve opening / closing lever 124 performed following the opening operation of the hydrant door 70 is an erroneous operation, and specifies the address of the identified fire hydrant device and causes the transmission units 4220, 4240 to transmit a control command signal including instruction information for operation guidance indicating that the operation is an erroneous operation and urging the user to remove the nozzle.

[0124] The terminal control device 58 of the fire hydrant device 20, which has received from the disaster prevention receiving panel 10 a control command signal including instruction information for operation guidance to inform the user that specifying its own address was an error and to urge the user to remove the nozzle, causes the control unit 150 to output, as an operation guidance to inform the user that the operation was an error, for example, a predetermined voice message from the speaker unit 98, such as "Beep, beep, opening the fire hydrant valve opening / closing lever is an error. Please return the lever to its original position," and causes the nozzle removal operation guidance display unit 134 to flash, and also outputs, as an operation guidance to inform the user that the nozzle is to be removed, which is the correct operation, a predetermined voice message from the speaker unit 98, such as "Beep, beep, please remove the nozzle from the nozzle holder and pull out the hose."

[0125] Therefore, the road user realizes that the opening operation of the fire hydrant valve opening / closing lever 124 was an error, returns the fire hydrant valve opening / closing lever 124 to its original closed position, and can recover from the error by correctly performing the operation and removing the nozzle 120. Then, as a result of this recovery operation, the nozzle detection switch 132 turns on and the valve opening / closing lever detection switch 136 turns off, so that the terminal control device 58, at the response timing following reception of the polling command signal specifying its own address, transmits to the disaster prevention receiving panel 10 a response signal including switch operation information that includes operation event information indicating the operation of the transmitter, the opening operation of the fire hydrant door, and the removal of the nozzle, but does not include operation event information indicating the opening operation of the fire hydrant valve opening / closing lever 124, that is, in which the first and fourth and fifth bit information from the beginning are set to bit 1 and the sixth bit information from the beginning is set to bit 0. The operation guidance control thereafter is similar to that already explained in "item e3," and therefore will not be explained further.

[0126] [f. Operation guidance control based on fire signals from fire detectors] Next, the operation guidance control when the disaster prevention receiving panel first receives a fire signal from the fire detector will be described.

[0127] When the transmission units 4210, 4230 receive an interrupt signal as a fire signal from the fire detector 16 and identify the address of the fire detector 16 that detected the fire, the control unit 40 of the disaster prevention receiving panel 10 specifies the address of a fire hydrant device 20 that corresponds to the detection area of ​​the fire detector 16 at the identified address, for example, that is installed in the detection area, and causes the transmission units 4210, 4230 to transmit a control command signal that includes instruction information for operation guidance to check for the fire and to prompt the user to report the fire by operating a transmitter.

[0128] When the terminal control device 58 of the fire hydrant device 20 receives a control command signal from the disaster prevention receiving panel 10, which includes instruction information for operation guidance to check for a fire for which its own address has been specified and to encourage the user to report the fire by operating the transmitter, the control unit 150 causes, for example, the transmitter operation guidance unit 96 to flash and outputs from the speaker unit 98 a predetermined voice message such as "Beep beep, please check for the fire. If you confirm the fire, please press the transmitter to report the fire."

[0129] Therefore, road users near the fire hydrant device 20 will receive a voice message from the fire hydrant device 20, confirm the fire, and press the button on the transmitter 88.The terminal control unit 58 of the fire hydrant device 20 will then send an interrupt signal to the disaster prevention receiving panel 10 when the button on the transmitter 88 is pressed.

[0130] Then, the disaster prevention receiving panel 10 detects both the fire detection by the fire detector 16 based on the interrupt signal already received from the fire detector 16, and the fire report by the response signal including the interrupt signal from the fire hydrant device 20 and operation event information indicating the operation of the transmitter, i.e., switch operation information with the leading bit information set to bit 1, and determines that there is a fire, causes the alarm unit 45 to output a fire alarm, and also controls the alarm display board equipment 30 to display a no-entry-to-tunnel message or the like, and causes the transmission units 4220, 4240 to transmit a control command signal including instruction information for guiding the door opening of the hydrant door 70 to the identified fire hydrant device 20. The operation guidance control thereafter is similar to the controls already described in "items e1 to e4," and therefore will not be described again.

[0131] [g. Operation guidance control when first operating the fire hydrant door to open] Next, the operation guidance when a road user first performs an opening operation on the fire hydrant door 70 without operating the transmitter 88 will be described.

[0132] In an urgent and chaotic situation such as when a fire breaks out inside a tunnel, it is conceivable that road users will first open the fire hydrant door 70 in order to use the fire hose 114 stored inside, without operating the transmitter 88.

[0133] In such a case, since the address of the operated fire hydrant device 20 is not specified in the disaster prevention receiving panel 10, when the terminal control device 58 of the fire hydrant device 20 detects that the door detection switch 74 is in the on state due to the opening operation of the fire hydrant door 70, it sends an interrupt signal to the disaster prevention receiving panel 10, provided that an interrupt signal has not been sent.

[0134] The disaster prevention receiving panel 10, which receives an interrupt signal based on the opening operation of the hydrant door, identifies the address of the hydrant device 20 that sent the interrupt signal, shortens the transmission period of the polling command signal to the identified hydrant device 20 compared to the normal monitoring state, and transmits the polling signal.The disaster prevention receiving panel 10 detects that the opening operation of the hydrant door 70 is an erroneous operation from the response signal that does not contain operation event information indicating the operation of the transmitter sent from the identified hydrant device 20, but does contain operation event information indicating the opening operation of the hydrant door, i.e., the first bit information is bit 0 and the fourth bit information from the beginning is bit 1, and transmits a control command signal to the identified hydrant device 20 that includes instruction information for operation guidance to check for a fire and to prompt the user to report a fire by operating the transmitter.

[0135] The terminal control device 58 of the fire hydrant device 20, which has received a control command signal from the disaster prevention receiving panel 10 that includes instruction information for operation guidance to check for a fire that has specified its own address and to encourage the user to report the fire by operating the transmitter, causes the control unit 150 to, for example, flash the transmitter operation guidance unit 96 and output from the speaker unit 98 a predetermined voice message such as "Beep beep beep, check for a fire before using the hydrant, and if a fire is confirmed, press the transmitter to report the fire."

[0136] Furthermore, opening the fire hydrant door 70 without operating the transmitter 88 is an incorrect operation in terms of operating procedures, but since it is not necessary to close the fire hydrant door 70 once it has been opened, no voice message is output indicating incorrect operation of the fire hydrant door.

[0137] For this reason, a road user who has opened the hydrant door 70 without operating the transmitter 88 will receive operation guidance from the hydrant device 20, confirm the fire, and press the transmitter 88, and the terminal control device 58 will transmit a response signal including operation event information indicating the opening operation of the hydrant door and the operation of the transmitter to the disaster prevention receiving panel 10 at the response timing following reception of a polling command signal specifying its own address. Note that, because the address of the fire hydrant device 10 that is the target of the operation guidance has already been identified, no interrupt signal will be transmitted even if the transmitter 88 is operated.

[0138] Furthermore, when the disaster prevention receiving panel 10 detects both a fire detection based on an interrupt signal sent as a fire signal from the fire detector 16 after separately detecting a fire, and a fire report based on operation event information indicating the operation of the transmitter included in the interrupt signal already received and the received response signal, and determines that there is a fire, it causes the control unit 40 to output a fire alarm from the alarm unit 45, and also controls the alarm display board equipment 30 to display a message such as "No entry to tunnel." Since it also receives operation event information indicating the opening operation of the fire hydrant door, the subsequent operation guidance control is similar to the already explained "items e2 to e4," and therefore a description thereof will be omitted.

[0139] [h. Control operation of the disaster prevention receiving panel regarding operation guidance] The control operation related to the operation guidance by the control unit 40 of the disaster prevention receiving panel 10 shown in Fig. 5 will be described. In this description, reference will be made to Fig. 6 and Fig. 7, which are flowcharts showing the monitoring control of the fire hydrant device by the disaster prevention receiving panel. The flowchart in Fig. 7 is a continuation of the flowchart in Fig. 6.

[0140] When the transmission units 4210, 4230 receive an interrupt signal as a fire signal from the fire detector 16, the control unit 40 of the disaster prevention receiving panel 10 selects and designates the address of the fire hydrant device 20 corresponding to the detection area of ​​the fire detector 16, and by sending a control command signal from the transmission units 4220, 4240, instructs the designated fire hydrant device 20 to output operation guidance instructing it to check for a fire and to prompt the user to report the fire by operating the transmitter (steps S1 to S3).

[0141] Next, when the transmission units 4220 and 4240 receive an interrupt signal from the fire hydrant device 20 based on the operation of the transmitter 88, the control unit 40 identifies the address of the fire hydrant device 20 that sent the interrupt signal (steps S4 and S5).

[0142] Next, when the control unit 40 detects operation of the transmitter based on operation event information indicating operation of the transmitter contained in the response signal from the identified fire hydrant device 20, it instructs the identified fire hydrant device 20 to output operation guidance urging the device to open the fire hydrant door by sending a control command signal from the transmission units 4220, 4240 (steps S6, S7).

[0143] Next, when the control unit 40 detects the operation of the transmitter contained in the response signal from the identified fire hydrant device 20 and the operation event information indicating the operation of opening the fire hydrant door, it instructs the identified fire hydrant device 20 to output operation guidance encouraging the removal of the nozzle by sending a control command signal from the transmission units 4220 and 4240 (steps S8 and S9).

[0144] Next, when the control unit 40 detects the nozzle removal operation based on the operation event information included in the response signal from the identified fire hydrant device 20, which indicates the operation of the transmitter, the opening operation of the hydrant door, and the removal operation of the nozzle, it instructs the identified fire hydrant device 20 to output operation guidance to prompt the opening operation of the fire hydrant valve opening / closing lever by sending a control command signal from the transmission units 4220, 4240 (steps S10, S11).

[0145] Next, when the control unit 40 detects the opening operation of the fire hydrant valve opening / closing lever based on the operation event information included in the response signal from the identified fire hydrant device 20, which indicates the operation of the transmitter, the opening operation of the fire hydrant door, the removal operation of the nozzle, and the opening operation of the fire hydrant valve opening / closing lever, the control unit 40 instructs the identified fire hydrant device 20 to output operation guidance encouraging the device to perform a water discharge operation by sending a control command signal from the transmission units 4220, 4240 (steps S12, S13).

[0146] This completes the series of control operations performed by the control unit 40 when the fire hydrant device 20 is operated in accordance with the correct operating procedure based on the fire signal received from the fire detector 16.

[0147] On the other hand, after the control unit 40 instructs the fire hydrant device 20 in step S9 to output operation guidance urging the removal of the nozzle, if the control unit 40 detects the opening operation of the fire hydrant valve opening / closing lever as an erroneous operation event without detecting the removal of the nozzle based on the operation event information indicating the opening operation of the fire hydrant valve opening / closing lever contained in the response signal from the identified fire hydrant device 20, the control unit 40 instructs the transmission units 4220, 4240 to output operation guidance stating that this is an erroneous operation by sending a control command signal, and also instructs the transmission units 4220, 4240 to output operation guidance urging the removal of the nozzle again in order to recover from the erroneous operation (steps S10, S14, S15, S9).

[0148] Furthermore, after identifying the fire hydrant device 20 that sent the interrupt signal in step S5, if the control unit 40 detects the opening operation of the fire hydrant door as an erroneous operation event without detecting the operation of the transmitter based on the operation event information indicating the opening operation of the fire hydrant door contained in the response signal from the identified fire hydrant device 20, the control unit 40 instructs the transmission units 4220, 4240 to output operation guidance indicating that it is an erroneous operation by sending a control command signal, and also instructs the transmission units 4220, 4240 to output operation guidance indicating that the fire has been confirmed and urging the user to report the fire by operating the transmitter in order to recover from the erroneous operation (steps S6, S16 to S19).

[0149] In addition, if the transmission units 4220 and 4240 do not receive a fire signal from the fire detector 16 but receive an interrupt signal from the fire hydrant device 20, the control unit 40 performs the control operations from step S5 onwards (steps S1, S20, S5 to S19) without performing the control operations of steps S2 to S4.

[0150] [i. Control operation of fire hydrant device related to operation guidance] The following describes the control operation related to the operation guidance by the control unit 150 of the terminal control device 58 of the fire hydrant device 20 shown in Fig. 4. In this description, reference will be made to Fig. 8, which is a flowchart showing the control operation by the terminal control device of the fire hydrant device.

[0151] As shown in Figure 8, the control unit 150 of the terminal control device 58 of the fire hydrant device 20 detects an operation event, and if an interrupt signal has already been sent from the transmission unit 148 to the disaster prevention receiving panel 10, causes the transmission units 4220 and 4240 to send a response signal including operation event information indicating the detected operation event to the disaster prevention receiving panel 10 (steps S21 to S23).

[0152] On the other hand, when the control unit 150 detects an operation event and has not transmitted an interrupt signal from the transmission unit 148 to the disaster prevention receiving panel 10, the control unit 150 causes an interrupt signal to be transmitted to the disaster prevention receiving panel 10 (steps S21, S22, S24).

[0153] Next, when the control unit 150 receives the control command signal transmitted from the disaster prevention receiving panel 10, it activates the corresponding display unit and provides operation guidance by outputting a voice message from the speaker unit 98 based on the operation guidance instruction information contained in the control command signal (steps S25, S26).

[0154] [j. Modifications of the present invention] Modifications of the disaster prevention system and the fire hydrant device thereof according to the present invention will be described. In addition to the above-described embodiment, the tunnel disaster prevention system and the fire hydrant device according to the present invention also include the following modifications.

[0155] (Monitoring of fire hydrant equipment by disaster prevention receiving panel) In the above embodiment, the control unit 40 of the disaster prevention receiving panel 10 detects an operation event based on the operation event information received from the fire hydrant device 20 and controls to provide operation guidance, but in addition to this, the operation status of the fire hydrant device 10 may be displayed on a screen on the display serving as the display unit 46 of the disaster prevention receiving panel 10 based on the received operation event information, making it possible to grasp the operation status of the fire hydrant device 20 on the disaster prevention receiving panel side 10. Furthermore, the control unit 40 of the disaster prevention receiving panel 10 may store the operation event history from the received operation event information in memory as history data, and read out the operation event history as needed so that it can be used to check and analyze the operation status of the fire hydrant device 20.

[0156] (Transmission Control) In the above embodiment, the disaster prevention receiving panel 10 uses half-duplex communication as an example of R-type transmission control between the fire detector 16 and the fire hydrant device 20, in which voltage-mode downstream signals and current-mode upstream signals are transmitted and received on the same transmission line (transmission line and common line). However, this is not limited to this, and full-duplex communication may be used in which the downstream transmission line and upstream transmission line (for example, the downstream transmission line, the upstream transmission line and the common line) are provided as separate transmission lines, and downstream signals and upstream signals can be transmitted simultaneously.

[0157] Furthermore, in half-duplex communication, when an interrupt signal is sent when a fire is detected by the fire detector 16 or when the transmitter 88 of the fire hydrant device 20 is operated, etc., the downstream transmission line and the upstream transmission line are separate in full-duplex communication, so a fire signal or fire report signal including the device's own address is sent as the upstream signal, rather than an interrupt signal. Also, in full-duplex communication, there is no need to separate the downstream signal and the upstream signal into voltage mode and current mode; both can be in the same mode, and full-duplex communication can be achieved by using a known transmission method.

[0158] (Operation guide) In the above embodiment, a guide display unit and a speaker unit are provided for the guidance operation to prompt the user to operate the fire hydrant device, but it is also possible to provide only one of them.

[0159] (Inspection work) In addition, regular inspections are performed on the fire hydrant device 20, and during these inspections, the disaster prevention receiving panel 10 can be set to an inspection mode, and as one of the inspection modes, fire alarm operations and linkage to equipment other than the fire hydrant device 20 can be stopped, allowing the user to check whether correct operating instructions are being output for operating the fire hydrant equipment of the fire hydrant device 20.

[0160] (Operation detection target) In the above embodiment, the detection targets are the operation of the transmitter, hydrant door, nozzle, and hydrant opening / closing lever provided on the fire hydrant device 10, and operation guidance is provided in response to the operation of these fire hydrant devices, but the fire hydrant devices to be detected are not limited to these, and may also include, for example, the fire extinguisher 140 stored in the fire extinguisher storage section 65 of the fire hydrant device 20 and the fire extinguisher door 78 provided on the housing 60.

[0161] More specifically, a door detection switch is provided on the fire extinguisher door 78, similar to the fire hydrant door 70, so that the opening operation of the fire extinguisher door 78 can be detected as an operation event, and a detection switch is provided on the bottom of the fire extinguisher storage section 65 in which the fire extinguisher 140 is stored, which is turned off when the fire extinguisher 140 is stored and turned on when the fire extinguisher 140 is removed, so that the operation of removing the fire extinguisher 140 can be detected as an operation event.
